Background
In September 2024, STONIMAGE received an inquiry from a U.S.-based restaurant group that operates multiple dining establishments across the Midwest. The customer was upgrading several back-of-house service areas and needed a compact and reliable food elevator (dumbwaiter) to improve the efficiency of food delivery between floors. The existing manual workflow caused delays during peak hours, and the customer was looking for a solution that would modernize operations while reducing labor intensity.
Customer Requirements
The customer outlined several key requirements:
A space-saving design suitable for a narrow shaft area
Smooth and silent operation to avoid disturbing guests
Stainless steel inner cabin meeting food hygiene standards
Stable lifting performance for continuous daily use
A durable control system with clear safety indicators
Given U.S. safety and restaurant operation standards, the client needed equipment that was compliant, easy to clean, and very stable during high-frequency operation.
After technical consultation and drawing confirmation, STONIMAGE provided a custom-built food elevator featuring:
A stainless-steel cabin with rounded interior edges for hygiene and easy cleaning
A reinforced guide rail and motor system designed for smooth, low-noise lifting
A dual-layer safety lock and overload protection system
A user-friendly external control panel designed for busy kitchen environments
A compact structure specifically optimized for the customer’s limited shaft size
Before shipment, each unit underwent repeated stress testing and factory simulation runs to ensure reliability under continuous operation.
The customer was very satisfied after receiving and installing the dumbwaiter. They reported that the food elevator:
Greatly reduced food delivery time between floors
Improved coordination between kitchen staff and servers
Operated quietly and steadily even during peak restaurant hours
Helped lower labor costs by reducing manual stair transport
Following the installation, the client informed STONIMAGE that they plan to continue upgrading their other restaurant branches and will consider additional dumbwaiter units for future projects.
This order not only strengthened STONIMAGE’s presence in the U.S. catering equipment market, but also demonstrated the reliability and adaptability of our food elevator solutions in real restaurant environments.
